Embodiment Construction

[0013]FIG. 1 depicts a number of preliminary activities for preparing the spoken fluency evaluation system. Part of the process involves gathering a speech sample from the person to be evaluated. This can be done in several different manners, for example, by having the person speak, ad hoc, on a given topic, or by engaging the person in a conversation, or by recording a live conversation of the person. The activities of block 101 involve creating topics for the person to speak on. Such topics may include asking the person to speak about their favorite movie, their favorite book, asking them to discuss their job duties, asking the person to describe the college or high school he / she attended, or other such topics familiar to the person. Having the person speak about a topic that the person is relatively knowledgeable about allows the person's fluency to be gauged without hesitation caused by uncertainty about the topic itself. In other embodiments the speech sample may be gathered by...

Abstract

A procedure to automatically evaluate the spoken fluency of a speaker by prompting the speaker to talk on a given topic, recording the speaker's speech to get a recorded sample of speech, and then analyzing the patterns of disfluencies in the speech to compute a numerical score to quantify the spoken fluency skills of the speakers. The numerical fluency score accounts for various prosodic and lexical features, including formant-based filled-pause detection, closely-occurring exact and inexact repeat N-grams, normalized average distance between consecutive occurrences of N-grams. The lexical features and prosodic features are combined to classify the speaker with a C-class classification and develop a rating for the speaker.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present invention relates to linguistics equipment and systems, and more specifically, to systems, methods and computer products for evaluating the fluency of a person speaking a language other than the person's native tongue.[0003]2. Description of Related Art[0004]Fluency evaluation can be used to assess the competence and effectiveness of people whose jobs depend on spoken communications, for example, call center agents, sales associates, technical representatives, or others who converse with the public as part of their job. Conventional methods of fluency evaluation typically analyze the speaking style of a person to detect the types and frequency of filler-words and discourse-markers used by the person. The results of the fluency evaluation may then be used to provide appropriate feedback to the person—e.g., the call center agent—to improve the person's job performance. Automatic fluency evaluation can also be used to evaluate ...
